        (flower)       (memetic)        
    travelers   from   a  parallel    
   world far beyond  ours...   
   an initial seed  places  a  
  forge.  then  starts  the melting,  
   the  gathering  of  materials  (the  
   secret ingredient in liquid glass  
  is blood, and in any  case,  
   a human host is needed for  
     interdimensional    travel).     
  after the entire plane is harvested,  
  comes the blooming phase where the  
  catboys spread  their  eggs  
  to  whichever other worlds   
   have  drifted  close,  and   the   
    cycle   continues,   elsewhere.
